Write one paragraph explaining the steps of photosynthesis

Plants and certain microorganisms use photosynthesis to create compounds such as carbohydrates. It's an endothermic (heat-inducing) chemical reaction that converts carbon dioxide to sugars using sunlight. Sugars are used by the cell as an energy source as well as a building block for other molecules. Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
